title: Neodymium:YAG laser anterior capsulectomy: surgical option in the management of negative dysphotopsia.
abstract: This report describes 6 cases in which neodymium:YAG (Nd:YAG) laser anterior capsulectomy achieved limited success in treating negative dysphotopsia. In 5 eyes with the Akreos AO MI60L posterior chamber intraocular lens (PC IOL), the dysphotopsia symptoms resolved completely (3 eyes) and partially (2 eyes) depending on the extent of the Nd:YAG laser anterior capsulectomy. In 1 eye with the Acrysof IQ toric PC IOL, the symptoms did not improve. Success with this procedure in patients with the Akreos AO MI60L PC IOL supports the role of the anterior capsule in the etiology and mechanism of negative dysphotopsia. Because the anterior capsulectomy did not resolve the symptoms in the patient with the Acrysof IQ toric PC IOL, the anterior capsule should be considered an optical risk factor for negative dysphotopsia and important in the manifestation of symptoms in only some patients. Other primary optical factors that have been described can presumably manifest negative dysphotopsia symptoms independent of light scatter from the anterior capsule.
